The really great thing about Marshall is that you know what you're going to get & you are NEVER disapointed. You just plug in & you don't have to look for the sound...it's there! Fantastic amps that deliver true world class sound, but at a reasonable price. I admit that some of the newer amps are not to my taste (too many knobs & switches), as I think that Marshall have tried to become all things to all men, when what they really excell at, is being...Marshall! Their valvestate range are IMO pretty dier, but I take it we are talking about their pro ranges.
I apreciate that a lot of forumites are looking for that '60's sound & as such turn to Vox or other combos, but I'm not looking for a '60's sound & you really have to hear a Ric through a 8x12 Marshall stack! I use a fair amount of overdrive, but I had a chap in the studio doing Shadows songs the other day & the Marshall through a 4x12 sounded amazing clean. Really warm & classy sounding. I have always preferred the 4x12 sound, with it's underlying sub bass, compared to a combo (especially an open backed combo), so 2 4x12's are even better live!
John, I like large power rigs, so you can turn all the way up & make some real noise!

Mine's got a master volume, so I can get a very good range of overdrive at not TOO rediculous a volume...it's a late '70's/early '80's model.
One of my first posts on the forum was expressing my opinion that Rickenbackers are as relevant today as they were in the '60's & are too often touted as being retro '60's machines, when in fact they are more than capable of competing with the very best modern gtrs. It's interesting that in my effort to find a contemporary sound, I am using both a gtr & an amp that have changed little in the last 50 years or so....
'Rickenbacker'...what a name! After all these years, it still thrills me.
